Tsehay Roschli Industrial and Agricultural Engineering (TRIAE)

Tsehay Roschli Industrial and Agricultural Engineering (TRIAE) is an Ethiopian company that manufactures agricultural equipment, building and construction materials, pre and post-harvesting equipment, dairy product equipment, and steelworks, aluminum, and stainless steelworks.

In 1986, Mrs. Tsehay Roschli founded Selam Children’s Village with 23 orphans and 4 workers in order to provide necessities and a family for children who lost their parents due to the drought that occurred in the northern part of Ethiopia. Following their daughter’s path, her parents, David and Marie-Louise Roschli, settled in Ethiopia in 1989 and began the groundwork for the technical and vocational center. Over the year, Selam continued to grow by supporting many people and employing hundreds.

To insure the sustainability of Selam children’s village projects, Selam Children's Village is involved in a variety of revenue-generating activities in the fields of construction, steelwork, renewable energy, hydropower equipment, transportation, agricultural, and woodwork. Selam Technical and Vocational College trainees gain hands-on experience through these revenue-generating projects. They gain confidence in their abilities in their field of study as they receive on-the-job training. Income-generating activities, on the other hand, reduce Selam's reliance on foreign aid.

Manufacturing low cost operation equipment through appropriate technology is a way to locally meet the immediate needs of the community.


TRIAE envisions becoming the most competitive business firm and the choice of customers by meeting and exceeding their needs and expectations.
